Abstract: A processing machine for performing a bending operation on a workpiece includes a die, a punch movable in a first direction for pressing the workpiece against the die, a slide member movable in a second direction perpendicular to the first direction, a first cam device that moves the punch toward the die for deforming the workpiece when being actuated by movement of the slide member, a second cam device that moves the punch for pressing a surface of the workpiece when being actuated by movement of the slide member. The pressure angle of the second cam device is smaller than a pressure angle of the first cam device. The processing machine further includes a drive member configured to move the slide member such that the second cam device is actuated after the first cam device is actuated.

Abstract: An offset fin manufacturing method for manufacturing offset fins includes a feeding step of feeding a strip plate, a connection forming step of forming a connection in the strip plate, and an offset fin forming step of bending a planar plate portion located between corresponding two of the connections. In the offset fin forming step, each offset fin is formed such that two of top surface portions, which are located at an upstream end and a downstream end, respectively, of the offset fin in a feed direction of the strip plate, are respectively and directly connected to corresponding two of the connections. One of two of lateral surface portions joined to a corresponding one of the two of the top surface portions is not offset, and thereby a length of the corresponding one of the two of the top surface portions measured along a wave continuation direction is increased.
